我必须将视频集成到我的 iPhone 应用程序中。与网上所有代码的区别在于，我必须显示视频并给用户播放它的机会。而不是自动播放它。

这就是我所做的：

- (void) play
{
    NSString *path = [[NSBundle mainBundle] pathForResource:@"video1" ofType:@"mp4"];
    NSURL *fileUrl1 = [NSURL fileURLWithPath:path];
    videoPlayer1 = [[MPMoviePlayerController alloc] initWithContentURL:fileUrl1];
    [videoPlayer1 setControlStyle:MPMovieControlStyleNone];
    [[videoPlayer1 view] setFrame:[self.view bounds]];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

    //[videoPlayer1 play];
    [self.view addSubview:[videoPlayer1 view]];    
}
- (void) moviePlayBackDidFinish:(NSNotification*)_notification
{
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:MPMoviePlayerPlaybackDidFinishNotification
                                                  object:nil];

    [videoPlayer1.view removeFromSuperview];
    [videoPlayer1 stop];
    [videoPlayer1 release];
    videoPlayer1 = nil;
}

但是屏幕只是变黑，没有显示任何其他内容。

除非我执行 [videoPlayer1 play] 什么也不会发生。但我不想自动播放视频......它必须由用户播放。那么，我应该如何操作才能显示视频（而不是黑屏）并在用户希望时播放它？谢谢

I have to integrate a video into my iphone app.The difference from all the code that there is on the net is that I have to show the video and give to the user the chance to play it.Not to play it automatically.

And here is what I have done:

- (void) play
{
    NSString *path = [[NSBundle mainBundle] pathForResource:@"video1" ofType:@"mp4"];
    NSURL *fileUrl1 = [NSURL fileURLWithPath:path];
    videoPlayer1 = [[MPMoviePlayerController alloc] initWithContentURL:fileUrl1];
    [videoPlayer1 setControlStyle:MPMovieControlStyleNone];
    [[videoPlayer1 view] setFrame:[self.view bounds]];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

    //[videoPlayer1 play];
    [self.view addSubview:[videoPlayer1 view]];    
}
- (void) moviePlayBackDidFinish:(NSNotification*)_notification
{
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:MPMoviePlayerPlaybackDidFinishNotification
                                                  object:nil];

    [videoPlayer1.view removeFromSuperview];
    [videoPlayer1 stop];
    [videoPlayer1 release];
    videoPlayer1 = nil;
}

But the screen just turn black and nothing else shown.

Unless I do [videoPlayer1 play] nothing happens.But I don't want to play the video automatically...it must be played by the user.
So, how should I act in order to show up the video(!not the black screen) and play it when the user wishes?Thanks
